Crossword Genius

Singer in white, normally (5)

Ross

I believe the answer is:

tenor

'singer' is the definition.
(tenor is a kind of singer)

'in white normally' is the wordplay.
'in' says the answer is hidden in the clue.
'TENOR' is hidden in the letters of 'white normally'.

(Other definitions for tenor that I've seen before include "Vocal range" , "Male voice (one of three?)" , "High male singing voice like Pavarotti" , "General drift or meaning" , "thread" .)

I've seen this clue in the Evening Standard.
